Transgrid has recently published a Project Specification Consultation Report (PSCR) for managing expected demand in the Panorama area of Central West NSW.

Network constraints are expected to arise from the connection of a new spot load (McPhillamys Gold Mine) to Essential Energy’s distribution network, and recent increases in the demand expected from this load. While the mine will be connected to the distribution network, the supply to the distribution network will be drawn from Transgrid’s nearby upstream Panorama Bulk Supply Point (BSP).

The McPhillamys Gold Mine is expected to be ready to connect from 2023/24 onwards, initially at 26MVA but forecast to grow to 35MVA by 2028/29. The expected additional demand from the mine will exceed the capacity of existing transmission and distribution infrastructure to supply the mine and the load in the general Panorama area, including the current capacity of the Panorama BSP.

Transgrid is required under the National Electricity Rules (NER) to perform joint planning with the relevant distribution network service provider to manage demand and provide prescribed transmission services. This requirement includes the identification of any limitations or constraints that affect the networks of both transmission and distribution network service providers.

The identified need for this investment is for Transgrid to ensure adequate supply to Essential Energy’s distribution network from the transmission network and address constraints that would otherwise arise from the connection of McPhillamys Gold Mine.

In the PSCR Transgrid presented three credible network options that would meet the identified need. A new connection point by establishing a three circuit-breaker switching station on 132kV Line 948 (Option 3) is found to be the preferred option to meet the identified need in this PSCR.

The estimated capital cost of this option is approximately $15.8 million +/- 25 per cent. Transgrid is the proponent of the proposed network project.

Transgrid welcomes written submissions on materials contained in this PSCR. Submissions are particularly sought on the credible options presented and from potential proponents of non-network options that could meet the technical requirements set out in this PSCR. Submissions are due on 10 March 2023.

In accordance with the requirements of the National Electricity Rules, a summary of the PSCR is made available on the AEMO website. A copy of the PSCR can be obtained from Transgrid’s website or by emailing
